Core Forms 4.3.8

New - Field names accept uppercase. The builder's Name field no longer force-lowercases input (HTML `name`/`id` are case-sensitive). Illegal characters are still sanitized. - Textarea options: Rows (height), Resize behaviour (default / vertical / horizontal / both / none), and a live character counter that shows "used / limit" when a Max length is set. An explicit Rows value now wins over the 5-line default height. - Phone (tel) value limits: new Min length, Max length, and Pattern controls to constrain accepted values.

Fixed - The builder's HTML generator silently dropped textarea min/max-length and conditional-logic attributes on save, so those validations were lost. The textarea output now matches the server-side renderer.
